RAMPAGE V EXTREME/U3.1

Perfect spacing and PCI Express 3.0 speed for incredible graphics!
Unleash the full power of multiple graphics cards for visuals that never stutter, with just the right amount of space between each card. Onboard switches let you selectively enable or disable cards in a flash — configuring multi-GPU setups has never been easier!

Drive CPU and DDR4 performance beyond the limits!
Designed to break performance barriers, ASUS OC Socket utilizes extra pins to connect a proprietary circuit to contacts found on Haswell-E's land grid array (LGA). Combined with our customized UEFI, this exclusive feature enables higher DDR4 memory frequencies, lower latencies and enhanced stability while overclocking, extending all the way to extreme overclocking conditions, such as Liquid Nitrogen (LN2). OC Socket is 100% compatible with new Haswell-E LGA 2011-v3 CPUs, ensuring the ideal combination of overclocking performance and compatibility.

Optimized for extreme overclocking
This is the first platform to support DDR4 memory, and it is capable of overclocking memory up to DDR4 3300+ MHz with all eight DIMMs fully loaded! ASUS-exclusive T-Topology circuit design plus patent-pending OC Socket unleash the full potential of DDR4 by minimizing crosstalk and signal reflections. Thanks to our expertise in motherboard layout design, signal timing issues are also greatly reduced, resulting in improved stability and overall performance. ASUS works with almost every DDR4 memory vendor to ensure the best compatibility – so you're assured reliable performance from your favorite brands.

Intuitive overclocking command center!
Get your hands on real-time system monitoring and tweaking in two modes. For both, a clear 2.6-inch display keeps you informed and in full control — so you can maximize the available power!

NORMAL MODE – easy system monitoring and performance boosts!
OC Panel can be installed directly into a 5.25-inch drive bay to provide real-time monitoring of multiple vital parameters, including CPU temperature, ratios, base clock and fan speeds. The CPU Level Up button provides instant control over two-stage overclocking, while CPU fan speeds can be adjusted to Turbo, Standard and Silent modes — super-simple controls, all at your fingertips.

EXTREME MODE — advanced overclocking made easy!
OC Panel can also be used as external overclocking console. In this mode, there are connectors and switches for exclusive ROG features including Subzero Sense, VGA SMB, VGA Hotwire, Slow Mode and Pause. You also have direct access to four-pin fans connectors – four in total! — as well as remote power and reset buttons.

Save more time, break more records
ROG understands overclockers better than any other manufacturer — so Rampage V Extreme includes all-new hardware-level Safe Boot and ReTry buttons to help put things right when overclocking adventures go wrong. They're quick, easy and real time-savers

Safe Boot Button
One quick tap of the Safe Boot button powers off your system and launches into Safe Mode, where you can tweak your retained previous settings.

ReTry Button
If your system hangs during the power-on self-test (POST) boot process, just hit the motherboard's hardware-level ReTry button to force a reboot right away.

Pump up your power
An extreme platform demands extreme control over the purest power, and nothing delivers more control or purer power than Extreme Engine Digi+ IV — Rampage V Extreme's exclusive voltage-regulator module (VRM).
MicroFine alloy chokes lower overall core loss for lower temperatures, while the VRM has been upgraded with the brand-new PowIRstage® IR3555. This chip integrates the driver, high-side and low-side MOSFETs and features the latest RDS On current-sensing technology.
Extreme Engine Digi+ IV's high-frequency pulse-width modulation (PWM) implementation scales to 1MHz allowing the DRAM VRM to achieve a 40% increase in stability!

Advanced fan controls for ultimate cooling and quietness
Rampage V Extreme has 8 x 4/3-pin (PWM/DC) combo fan connectors, four intelligent onboard sensors plus three additional 2-pin headers and a selection of three thermal cables to help you monitor the temperatures of up to seven motherboard or key components in real time — so you're able to adjust CPU and case coolers automatically or manually for the best dissipation.

Precision-engineered audio that's as great as a dedicated sound card
ROG knows the importance of flawless audio – pristine effects and full-range soundtracks make the game. That's why we invest substantial engineering resources to perfect onboard audio. The result is SupremeFX. Cutting-edge isolation technologies minimize electromagnetic interference (EMI) and exceptionally premium components deliver best-in-class audio that's as great as a dedicated soundcard. But we never rest on our laurels, which is why SupremeFX 2014 has been refined even further for Rampage V Extreme. That means even finer components and superbly clever software innovations for gaming and multimedia experiences beyond compare

1. 28-LANE CPUs can only support up to 3-Way SLI™/ 3-Way CrossFireX™2. The PCIE_X8_4 slot shares bandwidth with M.2 x 4. 40-LANE CPU: The PCIeX8_4 slot can only be used in x4 mode or lower when used simultaneously with the M.2 connector. If x8 mode is used, the two connectors will be mutually exclusive.28-LANE CPU: The PCIE_X8_4 slot will be disabled and the M.2 connector will always be enabled.3. The PCIE_X4_1 (gray) slot shares bandwidth with the PCIE_X1_1 slot, USB3_E910 and SATAExpress_E1 connector. When the PCIE_X4_1 slot is occupied by an X1 or X2 device, the SATAEXPRESS_E1 will be disabled. When the PCIE_X4_1 slot is occupied by X4 device, the SATAEXPRESS_E1, USB3_E910 ports, and the PCIE_X1_1 slot will be disabled. 4. Due to chipset behavior, the SATA6G_78, SATA6G_910 ports do not support IRST including RAID configuration.5. These functions will work depending on the CPU installed.6. These SATA ports share bandwidth with the PCIE_X4_1 slot, and when the PCIE_X4_1 slot is ocuupied, the SATA ports will be disabled. These SATA ports are for data hard drives only. ATAPI devices are not supported.7. 2 x USB2.0 port at mid-board shares with ROG extension (ROG_EXT) port.8. USB3_E910 ports at back panel will be disabled when the PCIE_X4_1 slot is occupied by an X4 bandwidth device.9. Extreme Mode capabilities, including V1, V2, DRAM and other voltage definitions, vary by chipset. Please refer to your motherboard manual for details.10. One 5.25" drive bay is required for NORMAL Mode installation.
